Question

A dealer sold 200 racquets. some were sold at rs 180 each and the rest at rs 330 each. the total receipts from these sales were rs 48000. how many racquests did the dealer sell at rs 180 each?

Answer 1

120

Explanation:

Number sold at rs180 = x

Number sold at rs330 = y

x + y = 200

180x + 330y = 48000

x = 200 - y

180(200 - y) + 330y = 48000

36000 - 180y + 330y = 48000

48000 - 36000 = 330y - 180y

12000 = 150y

12000/150 = y

y = 80

x = 200 - 80

x = 120
